Abstract (en)
[origin: EP3388721A1] An object of the present invention is to provide a three-way valve including a valve member for supplying heating water and a valve member for performing a bypass function and configured to independently operate the valve members to provide improved durability. To this end, the three-way valve includes a valve housing in which an inlet through which heating water is introduced, a first outlet configured to supply the heating water introduced through the inlet to a heating target area, and a second outlet configured to supply the heating water introduced through the inlet to a hot water heat exchanger are integrally formed; a first valve member configured to be opened or closed so as to selectively open any one of the first outlet and the second outlet; a drive unit configured to provide a driving force to open or close the first valve member; and a second valve member configured to, when a pressure of heating water of a side of the first outlet is higher than a set pressure in a state in which the first valve member opens a side of the first outlet and closes a side of the second outlet, open a bypass hole to allow the heating water to flow toward the second outlet and be operated independently from the first valve member.
